Iron Removal Process for High-Purity Silica Sands

In this article, a leaching study, carried out on a quartz sample to obtain high-purity silica sands, has been presented. A leaching process by using oxalic acid to remove low iron content from the ore under study and to obtain a material suitable for fiber optic production has been evaluated. A characterization study has been carried out to establish the location of the iron impurities on the ore: 77 g/t was the maximum iron contamination, whereas, a final iron

Removal Iron from Silica Sand to Get High Purity of Silica

When an sonication field is used in the acid leaching process, the mechanical interaction between the sound waves and the liquid would lead to the phenomena of cavitation and acoustic streaming. The mechanism of sonication assisted acid leaching is schematically shown in Fig.1. Because many gas molecule gather in defects and cracks of silica sand, they can easily turn into the nuclei for

Iron Removal Process for High-Purity Silica Sands

Innovative technology for the production of high-purity

01.05.2019· The production of high purity silica out of natural sand plays a critical role as a starting material in the industry of glass and high grade silicon. In this paper, we expose a novel processing method for the purification of sand silica. This method is a subsequent combination of thermal treatment and acid leaching. Firstly, samples of Tunisian natural sand were submitted to a rapid

Impurities removal process for high-purity silica

This study presents a novel chemical process for the extraction of high purity silica from diatomite. The process The process involves leaching of raw diatomite with acid prior to alkali

Removal of silicon in acid leaching and flocculation

01.07.2014· The remaining SiO 2 is then removed by acid leaching and flocculation, which is critical for high-purity ZrOCl 2 ⋅8H 2 O production. In a previous study that has adopted acid leaching only, the silica gel used completely precipitates within 48–72 h, and the remaining silica concentration is still high. The method is also time consuming and involves crystallization and filtration twice
